The environment influences to shipborne optical-electronic equipment such as carrier swaging

weapon shaking

fog or atmosphere

cloud and mist

wave of sea

it can result in tracking failure. According to this phenomena

a full information system that can offer high precision second lead to servo and control LOS to track ultralow-altitude target is manufactured. CA model

limited memory least-squares filter and the technology of " Approximate-comparative" ultralow-altitude are combined

then tracking ultralow-altitude target and offering angle information of losing target to servo especially called full information strategy is introduced. The designing and accomplishing of hardware platform are discussed in the text. The experiments prove that the full information system not only offer the information provided by outer system and feedback the data provided by shipborne Optical-electronic equipment to outer system

but also offer second lead data to servo system

the precision of data is advanced 11.8' to radar for 6 s.The model has the ability to control LOS to track ultra low-altitude target.It carries out a no-man guard and automatic shipborne optical-electronic equipment.
